OPA2670 具有电源控制的单端口、高输出电流 VDSL2 线路驱动器
The OPA2670 provides the high output current and low distortion required in emerging xDSL and Power Line Modem driver applications. Operating on a single +12V supply, the OPA2670 consumes a low 30.5mA quiescent current to deliver a very high 700mA output current. This output current supports even the most demanding xDSL requirements with greater than 450mA minimum output current (+25°C minimum value) with low harmonic distortion. Differential driver applications deliver less than –71dBc distortion at the peak upstream power levels of full-rate ADSL. The high 320MHz bandwidth also supports the most demanding VDSL2 line driver requirements.
Power control features are included to allow system power to be minimized
